Description
This is an update for tbuser's awesome pin library. I've been making enough use of these that I found a few changes that I think improve them significantly, though this should still function as a drop-in replacement for the V2 library. For all the people who've had trouble cramming the pins into my heart gears, this may help you make easier pins.
The primary changes are:
1) Wider gap keeps the pin nubs from getting jammed in a tight hole
2) Tolerance parameter on the pin side (instead of the hole side) because it's easier to reprint new pins if the fit is wrong
3) Extra tolerance parameter on holes (only for loose fit)
4) A fixed hole option that completely prevents rotation
5) Pinshaft module for making solid pin sections for longer pinpegs
6) Different pin sizes now have a more consistent shape
7) Minor changes to hole shape

Instructions
Put pins.scad in your working directory and call it with the "use" command in your OpenSCAD file. Read through pins.scad for directions on using the modules (it's mostly very similar to tbuser's original).
UPDATE: At the request of PrettySmallThings, I've made this library customizable. That won't affect its usage in OpenSCAD, but now you can export custom pins and holes using Customizer, to import into your other CAD programs. I still suggest learning OpenSCAD, but now you can avoid it a little longer.

Would you be willing to upload the "hollow" part of this file as an STL? Open SCAD is on the learning list, but not there yet. 123D online now supports STL imports, and I'd love to be able to use this to do some boolean operations on parts to coordinate with your pins.
Good idea. I did you one better and made the library customizable, so you can export whatever pins or holes you might need, without needing any OpenSCAD knowhow.
